Business Phone Systems
Legacy Support
Service, repairs and replacement handsets for Avaya, Nortel and NEC systems that are no longer manufactured, plus help planning your move to a new system.
Even though some Avaya and Nortel systems are no longer manufactured, we still service, maintain, and support them for the businesses that rely on them every day — repairs, moves, adds, changes, replacement handsets, and help planning a migration when you’re ready for one. If your system is one of the models below, we can help.
